At the 2018 European Forum for Electronics Components and Systems (EFECS), Horizon 2020 consortium CAPID has demonstrated prototypes of paper products augmented with new electronic functionality – Capacitive ID (CAPID). It’s the industry’s first demonstration of CAPID technology, which integrates electronics into paper making it possible to connect the paper product to the internet via a touchscreen device.

CAPID is a system through which a tiny, flexible tag is inserted into an object. That object — which could be as small as a card or a label — can then be identified when placed on a touchscreen. The CAPID project’s aim is to develop a new generation of wireless tags that bring something different and valuable to touchscreen technology.

The tags – called ‘C-tokens’ – are thin and flexible, metal-oxide tags, integrated into paper and plastic products. They send a dynamic capacitive signal into the reading devices which make it possible to identify and locate low cost and high-volume products, like cards or labels, to the internet, just by putting them on a touchscreen.

Every C-token tag will have its own ID. A potentially vast number of tags, all of them identifiable, will make it possible to create unique codes for any product. C-tokens have a very small footprint making it possible to integrate them in a product as thin and flexible as a playing card. They are also more secure than other machine-readable technologies such as QR (quick response code — a type of barcode read by an imaging device), which can be copied, or NFC (near-field communication — common in contactless payment), which can be read from a distance.

The CAPID project brings together a number of players, from the worlds of research, technological innovation and manufacturing. Three of them will be developing the enabling technology for C-token devices. They are Cartamundi, the world’s leading manufacturer of card and board games; Imec, a research and innovation hub in nano-electronics and digital technologies; and TNO, an independent research organization.

Real life applications will be demonstrated in three concrete product prototypes: board games (through Cartamundi Digital, which creates unique applications for mobile and online usage), an example of which was demonstrated at the EFECS Conference; ticketing and access control (through Simply-X, an information technology and services company); and mobile payments (through Rebased, which offers programming expertise).

The technology opens up the potential for these three areas. Taking what was good in the traditional gameplay of board games, this adds possibilities through digital and online concepts e.g. digital animation and up to date changes, connected and immersive new game experiences.

From a ticketing perspective, CAPID enabled cards will offer event solutions beyond just the physical event itself, creating an entire experience for guests even after the event in combination with their smartphones. It will also enable event organizers and venue owners to have true end-to-end access control from authorizing a guest to a physical space or section as well as authorizing a guest via their mobile device.

The new CAPID enabled mobile payment system aims to liberate data that is currently restricted for use by leading providers (i.e. Visa, MasterCard etc.) while respecting European privacy laws – no personal data is exchanged. This opens up the potential for event or venue owners who don’t have access to transaction data. In addition, the technology will allow any smartphone or capacitive touchscreen to become a payment terminal.

The CAPID consortium is made up of a series of partners, supported by Horizon 2020, the biggest EU Research and Innovation program ever with nearly €80 billion of funding available over seven years (2014 to 2020) – in addition to the private investment that this money will attract. It promises more breakthroughs, discoveries and world-firsts by taking great ideas from the lab to the market.
